    Hi everyone! I am setting up a 5 gallon/19 liter CO2 tank and - after doing some research (including on this forum) - want to keep my substrate PAR at about 30-50 umols to keep some semblance of stability in the tank. My question is, are there any plants that will readily turn red under such conditions, assuming everything else is being done properly? Thanks :)

    Thanks :) Do those plants need nitrate limitation to turn red? Or will they simply turn red under any 'decent' high tech setup with ample nutrients and CO2?

    Jup they turn red easily, no limitations needed. Just a right balance of co2 light an nutrients..

    Thanks :) By the way...about how much (in ppm) should I dose to a tank like this? How much nitrate, phosphate, potassium, etc? I was pretty sure the traditional EI method was intended for a more brightly lit tank than this.

    It depends, what kind of substrate do you haven AS or inert. You can always try to dose half of EI end increase if you have signs of lack in nutrients..

    I am using a substrate consisting of 2 parts sand, 1 part cat's pride clay cat litter (which has, remarkably, not turned to mush underwater...it remains as discrete pebble-like structures) and 1 part topsoil. I can try half the EI dose...thank you.

    Using Co2 opens up the options to red plants. I would think Rotala macranda would be easy. L. Super Red mini and the Alternanthera are classic.
    Why Co2 for such a small tank? I would go at least a 20 gallon. I'm not so keen on nano. 20 gallons is nano enough for fish and for a decent variety of plants.

    My landlord will not allow me to have more than 20 gallons of aquarium indoors...I have no choice but to use little tanks like this, as limiting as they are.

    You might skip fish that can't really look too natural moving and instead keep those colorful shrimp. There isn't a month that goes by that I dont I think of making a shrimp tank. One day. I lke the red and white ones..but blues are tempting.
